To all whom t may concern:

Be it known that I, ERAsi'fUs E. Wiiyiinsr, citizen of the United States, residing at Lynn, in the county of Essex and State of pertains to make and use the saine.

The present invention relates to certain new and useful improvements in automatic' sole'le'velin'g machines, and more particularly tothe jack adjusting mechanism employed upon such machines. Sole leveling j machines of this general type are provided with mechanism for oscillating the shoe supporting jacks automatically beneath the leveling rolls, manually operated means being provided for .adjusting this mechanism in order tov vary the oscillations of the jack as desired. In the present type of machine, however, the manually operated control is located in the lower part of the machine and is not conveniently accessible to the hand of the operator when it is found necessary to use it. 4

The object of the present invention is to provide a jack adjusting mechanism to which the operator may have convenient access and which is simple and eflicient in its operation.

lVitli the above object in view, the invention consists of 4the features of construction which will be described in thc following specification and defined in the appended ilaims.

In the accompanying drawings illustrating the preferred form of the invention Figure 1 represents aside elevation of an automatic sole leveling machine with the improved jack adjusting mechanism applied thereto. Fig. 2 is a detail with a portion in section, showing a front view of the adjusting mechanism.

Referring to the drawings in which like characters 'of refeience indicate like parts, 1 represents the frame of the machine, 2 the leveling rolls, 3 the roll carriers and 4l. the roll carrier beds pivotally mounted at 5 upon the` frame of the machine, so as to be free to tip longitudinally. The rolls 2 arc given rapid reciprocating or vibrating movements in the roll carrier-s 3 through suitable connections from the driving shaft 7 mount- Speciileatioii of Letters Patent.

ed in bearings in the upper rear portion of themachine frame and constantly rotated by a driving pulley 49 secured to the shaft.

yThe-carrier beds are acted upon `by springs 10 to swing the beds on their pivot 5 and press the leveling rolls against the soles of the shoes on the' shoe supporting jacks. The shoe supporting jacks are represented at 11 and are arranged to oscillate beneath the leveling rolls,-as will be hereinafter described. Eaoh of the jacks 11 is loosely pivoted by means of sleeves 17 upon a shaft 18 journaled in the front portion of the inachine flame. Situated between the sleeves 17 on the shaft 18, and loosely mounted thereon, is a sleeve 19, to which is` secured a downwardly extending arm 20. Adjustably mounted in an arc-shaped slot in the arm 2O is a slide block 21, to which is pivotally connected a link 22, the otherend of which is provided with a roll engaging a path cam 23, secured to a wheel or disk 15,

and which 'is pivotally connected to the upper i end of an arm or lever 24, pivoted at 25 in the rear lower portion of the machine frame. By this construction, as the shaft 16 is rotated, the sleeve 19 will be oscillated, and if either jack is connected to the sleeve, the jack will be oscillated beneath its corresponding leveling i'oll. When the jacks are disconnected from the sleeve 19, they fall back of their own weight and rest against sto s 26 carried by brackets extending fonwar ly from the 'machine'frame For connecting either jack to the sleeve 19, so as to be oscillated thereby beneath its corresponding leveling roll, the sleeve 19 is provided with ra-L- dially extending Iarms 27', the outer ends of which are connected by va 'hollow rod 28, in

which are seated spring pressed pins 2i),` only one of which isshown Vin Fig. 2,4 theA ioo had for a full description of the construction and inode of opeiation.

it lis desirable to vary the travel ot the shoe supporting jack -when operating upon dierent classes of Work, and the present invention comprises an improved mechanism. for accomplishing this result expedi-i a spring pressed lateh`37 of any convenient foi'm. T he latch 37' is 'adapted to engage Witha toothed segment 38, which is rigidly mounted upon the sleeve 19 to oscillate therewith. The block 2l may .be usted to rany position in the slot 32 by moving the handle 35, the mechanism being retained in this adjusted position by the spring pressed latch 37 engaging with the toothed. nient 38. j

Having thus described the invention, what is claimed. as new is l. 'A sole leveling machine having, in combination, a leveling roll, a .shoe support-- ing jack, a shaft about which the jack is oscillated, a depending slotted arm foi' oseillating the jack, a slide block supported in the ai-in, an adjusting lever iulci'uined upon the' shaft and having a handle conveniently accessible to the operator, means for locking the level in adjusted. position, and connections between the lever and slide block int-stese toadjust the slide block in the aiin and vary' the oscillations of the jack.

2. sole leveling machine, having, in combination, leveling rolls, a plurality of shoe supporting jacks, a shaft about Which the jacls osciliate, actuating mechanism for the jacks, comprising a .sleeve mounted upon the shaft between the jacks, aslotted arin depending from the sleeve, a slide block adjust-ably held in the slotted arm, Ineens ytor actua ting the block to oscillate the sleeve,

means for operatively connecting either jack to the sleeve, and mechanism mounted upon. the shaft -independcntly ot the jacks and :.idapted to adjust the slide block in the slotted ai'in, substantially as described.
